Visualising the Guardian Datablog | Information Is Beautiful"There’s been a furore over here in the UK about the dangers of illegal drugs. The Government has sacked its most senior drugs advisor, Dr Professor Nutt, after he claimed cannabis was no more harmful than alcohol. And that horse-riding, and specifically ‘equasy’ (Equine Addiction Syndrome) was riskier than taking ecstasy. (Statistically he’s correct. His study here.).

Anyway, digging at the numbers behind his statements and how drugs are reported in the popular press, I found some stuff I didn’t expect about drug harms."tags: visualization"You're fired.

K12_SocialNetworkingSurvey.pdf (application/pdf Object)To benchmark attitudes, perceptions and
utilization of social networking websites
and content-sharing tools by teachers,
principals and school librarians.tags: web2.0, media, statistics, k12_socialnetworkingsurvey, socialnetworkingnielsen_howteensusemedia_june09.pdf (application/pdf Object)It’s easy to get caught up in the hype
around teenagers. The notion that teens
are too busy texting and Twittering to be
engaged with traditional media is exciting,
but false.
To develop the best strategy around
teens and media, start by challenging
popular assumptions about teens. Don’t
focus on the outliers, but on the macrolevel
trends of media and preferences for
the segment. The averages will show you
that teens can often be reached by the
same means as their parents.
In this report, “How Teens Use Media,”
we debunk the myths and give you the
hard facts.tags: web2.0, teens, media, statistics, debunk, myths

The ECAR Study of Undergraduate Students and Information Technology, 2009 | EDUCAUSE"Since 2004, the annual ECAR Study of Undergraduate Students and Information Technology has sought to shed light on how information technology affects the college experience. We ask students about the technology they own and how they use it in and out of their academic world. We gather information about how skilled students believe they are with technologies; how they perceive technology is affecting their learning experience; and their preferences for IT in courses. The ECAR Study of Undergraduate Students and Information Technology, 2009 is a longitudinal extension of the 2004, 2005, 2006, 2007, and 2008 studies. It is based on quantitative data from a spring 2009 survey of 30,616 freshmen and seniors at 103 four-year institutions and students at 12 two-year institutions; student focus groups that included input from 62 students at 4 institutions; and review of qualitative data from written resp…

cyoa visualizedVisualization of choose your own adventure books

At its atomic level, a cyoa book is a collection of numbered pages of a few different types. Most pages tell a portion of the story, then finish by telling you to jump to another page. A smaller number of pages tell a conclusion to the story and represent an endpoint with no further jumps. We can subdivide these ‘narrative’ and ‘endings’ groups further based on the number of choices offered or the goodness of the ending. To visualize this, imagine color-coding every page in the book and then laying the pages out next to each other:tags: libraries, cyoa, books, visualization, tear out the pagesDangerously irrelevant libraries - Home - Doug Johnson's Blue Skunk Blogtags: libraries, books, questions, library, education, 10, web2.0, irrelevant libraries, dangerously, home10 questions about books, libraries, librarians, and schools - Dangerously Irrelevant10 questions about books, libraries, librarians, and schoolstags: lib…

Cell Size and ScaleDemonstrates Scale of items ranging from a grain of rice down to an atomtags: science, cells, biology, scale, Interactive, size, genetics, atomCoSN VOIK-12 technology leaders are under increasing pressure to justify current and proposed technology expenditures. Value of Investment (VOI) is a CoSN project to help schools to better understand the costs and benefits of proposed technology related projects. Much as corporations use Return on Investment (ROI) to evaluate the worth of these projects, schools should perform a similar evaluation. However, there is a fundamental difference between K-12 and business goals: a business exists to make money; business technology projects are in place to increase top line revenue and/or decrease overall costs. The business of schools is education; schools need to understand their educational goals and how investments in technology will support them.tags: edtech, technology, research, assessment, planning, indicators, tco, voi

Brain Research and Visual Learning

I had the opportunity to hear Wes Fryer keynote today at the 1-1 Laptop Conference in Chicago. He used a stat that I have heard before and have debated a little.

The idea is:

"What we see travels to the brain 60X faster than what we hear"

We discussed it afterward because I have recently looked at that information for another presentation that I was working on. I think it should actually be:

"At any one time 60X more information can travel to the brain from the eyes than from the ears"

Did some research tonight to confirm my off the head numbers today and here is what I found...

Optical nerve fibers = 1,200,000
Several spots on the web - here it is from Wikipedia: http://en.wikipedia.org/wiki/Optical_nerve

Auditory nerve fibers - 20,000 - 30,000 depending on the source
wikipedia has it at 30K

At 20K you get the 60X number

1,200,000/20,000 = 60

That would just impact the amount of information that could be carried at any one time. It is all electrical impulses traveling somewhe…

nsf.gov - Funding - Innovative Technology Experiences for Students and Teachers - US National Science Foundation (NSF)The ITEST program responds to current concerns and projections about the growing demand for professionals and information technology workers in the U.S. and seeks solutions to help ensure the breadth and depth of the STEM workforce. ITEST supports research studies to address questions about how to find solutions. It also supports the development, implementation, testing, and scale-up of implementation models. A large variety of possible approaches to improving the STEM workforce and to building students’ capacity to participate in it may be implemented and studied. ITEST projects may include students or teachers, kindergarten through high school age, and any area of the STEM workforce. Projects that explore cyberlearning, specifically learning with cyberinfrastructure tools such as networked computing and communications technologies in K-12 settings, are of special in…

Oversold and underused: computers in ... - Google BooksLarry Cuban's Oversold and Underused on Google Bookstags: instruction, improvement, capacity, instructional_capacity, underused, oversoldinstruction capacity improvement.pdf (application/pdf Object)three decades
of research has found that only a few interventions
have had detectable effects on instruction
and that, when such effects are detected,
they rarely are sustained over time.
A review of research and professional experience
with school improvement suggests
several explanations for these disheartening
findings. One is that schools are complex
social organizations situated within, and vitally
affected by, other complex social systems
including families, communities, and
professional and regulatory agencies. The
larger social environment of schools constrains
and shapes the actions of teachers,
students, and administrators, often in ways
that greatly complicate the work of school
